One thing about Lord Balrus was he always kept weird sigils and seals inside his manse. Most of these seals had no meaning, and they belonged to no great kingdom or any Lord. He used his rodents and skilled craftsman to make these seals, and they always came in handy when he wanted to send anonymous letter.
This time two riders were sent to Raven, and they were instructed to make it in less than three days. Hence that meant they had to sail alongside the Silent Sea towards small towns in the North, and then the ride won't be long to the capital. This was a shortcut that most people who hated riding for days in the heat and cold used, but it came with a cost.
